IMPROVEMENT IN ATTACHING PLOW-COLTERS.

Specificationforming part of Letters Patent No. 93,888, dated August 17,1869.

To all 'whom it 'may concern:

Be it known that I, DAVID W. HUGHES, of Palmyra, in the State ofMissouri, have invented a new and useful Improvement in AttachingGolters and Gage-Wheels to Plows, and I do hereby declare that thefollowing is a full, clear, and exact description of the saine,reference being had to the accompanying drawings, and letters ofreference marked thereon, making apart of this specification, in which-Figure l is an elevation of the sleeve, with a longitudinal verticalsection of the hub. Fig. 2 is a central section of the clampingplate,and Fig. 3 is a plan view of the larger end of the tapering` journal.

To enable those skilled in the art to make and use my invention, I nowproceed to describe its construction and operation.

Similar letters in the drawings refer to like parts.

This invention consists in making in the hubs of circular revolvingplow-colter or gage-wheel conical apertures, and in providing conicaljournals, which may be kept always closely litted in the apertures, soas to prevent wabbling of the colter or wheel g also, in an improvedform of lock for attaching said journals to the colter or wheel yoke, sothat they may not turn with the colter or wheel 5 also, in a sleeve forconnecting the colter-yoke with the plow-beam, that is at oncehexagonal, so as to present a flat side to the beam whichever way it maybe turned, and eccentric, so as to fix the yoke and colter at a greaterorless distance from the side of the beam, as may be desired.

In the drawings, A is the plow-beam, and B the plow-colter. The latteris mounted in a yoke, consisting of a cylindrical rod, a, bifurcated atits lower end, the colter being placed between the forks, and runningupon an axle connecting their ends.

On each side ot' the colter, and at the center thereof, is a boss, b,which serves as a hub, through which is made an orifice tapering inward.

Within said tapering orifices are placed conical journals e, made ofwood, rawhide, or metal, as desired, with central orifices for the axleof the colter to pass through.

Across the larger ends of the journals c are made grooves for thereception of the lianges d', turned down along the sides of the platesd, which plates have other flanges, el, turned downin the oppositedirection across the ends, and between the flanges d" are placed theends of the forks a of the colter-yoke. The lianges d prevent the platesel from turning with the hubs, and the flanges d prevent the journals cfrom turning.

Nuts are placed on the ends of the axle, outside the forks a', and bymeans of these, when the journals become too loose in their conicalbearings, they may be tightened.

The cylindrical rod a enters an aperture made for its receptionlongitudinally of the sleeve e, and at one side of the center thereof,so as to make the said sleeve eccentric with respect to the rod;therefore, by turning the sleeve e more or less, the yoke a and coltermay be brought nearer to or farther from the side of the plow-beam, asmay be desired, in order to vary the width of the cut made by the plow.

The sleeve c is fastened to the plow-beam by means of a pair of metallicloops, c e', through which the sleeve passes, placed one above and theotherbelow the plow-beam, and having their bodies or handles-inserted inthe slotted plate e on the other side of the plowbeam, and having nutson the ends of said bodies or handles, by means of which the sleeve issecured to the plow-beam.

The sleeve is hexagonal or otherwise manysided, so as to always presenta iiat side to the plow-beam, and be the more readily held in place bythe loops and nuts.

The yoke a is held in place in the sleeve e by means of a nut on itsupper end, where the same protrudes above the top of the sleeve, and bythis means the yoke may be clamped fast to the sleeve, or may beloosened therein and allowed to adjust itself to the line of draft.

What I claim as new, and desire to secure by Letters Patent, is-

1. Providing the hubs of the colter or wheel B with conical journals cand bearings b, as and for the purpose described.

2. In combination with the conical journal c, the lock-plate d,constructed and operating substantially as described.

3. rI`he hexagonal sleeve e, as and for the purpose set forth.

DAVID W. HUGHES.
